Issue with the CBs is pace (or lack of) but then we can't play too deep and just look to soak pressure like we did at the start of the season and end of last because we have no quality up top.And then on top of that you have CBs who can't or won't step forward and compact that space. And also the wingers don't push high up either so eventually enough time and space opens for them to break the lines. A complete system failure.
I keep seeing people say we need to go back to how we played in April etc but the key difference is we had Richarlison. It wasn't exactly great then but we managed to eek out some results because we had genuine quality in the final third.
